Beckman, Fowler, Kans. Application December 12, 1949, Serial No. 132,562 3 Claims. '(01. 74-5625) My invention relates to an improvement in auxiliary accelerator foot pedal for vehicles. An object of my invention is to provide a device of the kind mentioned that may be installed in an automobile either as regular equipment or as an accessory.

Afurther object of the invention is to provide a device of the kind mentioned that will provide means for accelerating the speed of the vehicle engine with either foot of the operator of the vehicle.

A still further object of the invention is to provide a device of the kind mentioned in which the linkage between the two foot accelerator pedals may be easily and quickly attachable and detachable for connecting or disconnecting one pedal to or from the other, the device being made so that this operation may be done without the use of tools.

A still further object of the invention is to provide a device'of the kind mentioned that is simple to make, one that is inexpensive, one that is easy to install, and one that is sturdy, long lived, efficient in its work as well as being easy and simple to use. These and other objects will be more fully described as this description progresses.

Now referring to the accompanying. drawings in which similar numerals of reference designate the same parts throughout the several figures of the drawings;

Fig. 3 is an enlarged detail top plan view of the auxiliary foot pedal device and its attachment to the primary or original accelerator foot pedal.

Fig. 4 is a top plan view of the auxiliary foot pedal support.

Fig. 5 is an upper end view of the primary accelerator pedal and illustrating one method of connection between the primary pedal and the auxiliary pedal.

Fig. 6 is a view the same as in Fig. 5 and showing a modified form of connection between the primary pedal and the auxiliary pedal.

Fig. 7 is a detail side view of the auxiliary foot A pedal and illustrating the design of mounting thereof Where a thick floor pad is used.

Fig. 8 is a detail side view of the auxiliary foot pedal and illustrating the design of mounting thereof where a thin floor pad is used.

In the drawings is shown the usual sloping floor element I6 of an automobile, the floor board .10 is covered with a thick floor pad ll, asshown in Fig. '7, or a thin floor pad I la as shown in Fig. 8. The usual or primary accelerator pedal is shown at I2 and is hingedly mounted at l3 to the floor board III in the usual manner. v

My improved auxiliary accelerator pedal and connection device therefor to the primary accelerator foot pedal consists of a shaft I4, one end of which is bent at a ninety degree angle to the shaft I4 to form a rockable lever element I5. The shaft I4 is revolvably carried in suitable bearing elements I6 and II that are rigidly attached to the floor element II] of the vehicle body by means of suitable screws, bolts or the like I8 to preferably hold the center axis of the shaft I4 in alignment with the center axis of the original or primary accelerator foot pedal supporting hinge I3. The other end of the shaft I4 is threaded as indicated at I9.

The device is provided with an auxiliary accelerator foot pedal support element 20. One end of the auxiliary accelerator foot pedal support 20 has a hole 2| therethrough through which the threaded end IQ of the shaft I4 slidably passes and nuts 22 and 23 that are threaded onthe threaded end I9 of the shaft I4 are turned each to bear one on one side of the auxiliary foot pedal support 20 and the other to bear against the other side of the auxiliary foot pedal support 20 to rigidly bind and hold the auxiliary foot pedal support element 20 in adjusted radial positions about the threaded end I9 of the shaft I4 for the purposes that will later be made obvious. The auxiliary foot pedal accelerator support 20 is preferably made L-shaped to allow for the thickness of the floor pad II through which the auxiliary accelerator foot pedal support will have to operate. The auxiliary pedal support plate 2::

, is provided with a pair of spaced apart curved slots 22' and 23' for purposes that will later be described. a

An auxiliary accelerator foot pedal 24 is positioned over and rests on the auxiliary accelerator foot pedal support 20 and bolts 25 and 26 are slidably passed through the lower end thereof and also through the slots 22' and 23' and nuts 21 and 28 are threaded on the bolts 25 and 26 to rig-idly bind and hold the auxiliary accelerator foot pedal 24 on the auxiliary accelerator foot pedal support element 20 in adjusted angular positions such as indicated by the dotted position 24a. This is a feature of importance since the angle of the auxiliary accelerator foot pedal 24 may be adjusted to the angle the drivers foot will normally take in using the auxiliary accelerator foot pedal and this makes for more comfort and accuracy in using the auxiliary accelerator foot pedal.

As shown in Fig. 3 the lever portion I5 of the shaft I4 is provided with an extension shaft 29, one end of which is threaded as at 30 and is threadedly screwed into a threaded hole in the end of the lever element I5. The extent to which the end 35 of the extension shaft 29 is screwed into the lever element I5 serves as a means of adjusting the length of the lever assembly I5--29. Rigidly fixed on the outer end of the lever extension 29 is a ball seat element 3I in which is seated a ball 32 that is rigidly carried on a pin element 33 that is rigidly carried by a pair of clamp elements 3 5 and 35 that are rigidly clamped onto the upper end portion of the primar accelerator pedal I2 so that when the auxiliary accelerator foot pedal 24 is pressed to rock downwardly the shaft I4 and lever I5293I will be actuated to likewise rock the primary accelerator foot pedal I2 downwardly to govern the speed of the vehicle in the usual manner. While the primary accelerator foot pedal I2 may be operated from the auxiliary accelerator foot pedal I2 as above described it is obvious that the primary accelerator foot pedal I2 may also be operated in the usual manner by the right foot of the operator of the vehicle.

In Figures 2 and 5 is shown a modified form of the linkage between the lever I5 and the primary accelerator foot pedal I2. In these figures is shown the clamp elements 34 and 35 which are 3 identical to those shown in Figures 2, 3, 5 and 6. The clamp elements 34 and 35 each consist of a hook-like formation A having a depending leg B and a threaded portion C of a pin 33, which is the same as the pin 33 in Fig. 3 and is threaded through the leg B of the clamp member 34 and slidably passes through the leg B of the clamp member 35, and a nut 36 is threaded on the threaded end of the pin 33 to bear against the leg B of the clamp member 35 to draw the two clamp members 34 and 35 toward each other and thereby tightly and rigidly hold them and the pin 33 or 33 on the primary accelerator foot pedal I2.

As shown in Figures 2 and 5, one end of the pin 33 extends inwardly and beyond the primary accelerator foot pedal I2 and is turned upwardly as at 31 and the lever I5 is made long enough to rest on the pin 33 thereby omitting the parts 29, 3I and 32 as shown in Fig. 3. If it is desired to disconnect the auxiliary accelerator foot pedal device from the primary accelerator foot pedal this may be done by taking hold of the upper or outer end of the lever I5, raising it and then springing and moving it in the direction of the dotted line and arrow D to the position I5a whereupon the auxiliary accelerator foot pedal 24 will drop to the floor Ii I and the lever arm I will do likewise.

The modification shown in Fig. 6 is the same as that shown in Figures 2 and 5 except that one end of the pin 33' is bent in a hook shape E with the opening F of the hook being directed toward the primary accelerator foot pedal I2 and the direction of the hand of the hook E being downward from the primary accelerator foot pedal I2.

4 The opening F of the hook E is slightly narrower than the diameter of the lever I5 that is resting in the hook E to insure the retention of the end of the lever I5 in the hook E.

To disconnect the auxiliary accelerator foot pedal device from the primary accelerator foot pedal the end of the lever I5 may be moved in the direction of the dotted line and arrow G and forced through the hook opening F and to the position I5b whereupon the auxiliary accelerator foot pedal will drop to the floor I0II and the lever I5 will do likewise whereupon the primary accelerator foot pedal may be used in the usual manner without the auxiliary accelerator pedal.

To be able to use the auxiliary accelerator pedal device on all automobiles it may be necessary to vary the spacing between the primary accelerator foot pedal and the auxiliary accelerator foot pedal in order to make the device fit the vehicle in which the device is to be used, or to fit the person that is to use the device. This adjustment may be made by screwing the nuts 22 and 23 away from the auxiliary accelerator foot pedal support 20 and then sliding the auxiliary accelerator pedal support 20 to the selected position and then rescrewing the nuts 22 and 23 to engagement with the element 20 to rigidly refix the support 20 on the shaft I4 in its radially adjusted position as hereinbefore described.

After the auxiliary accelerator foot pedal device has been installed as above described the floor pad II is cut to provide for the passage of the auxiliary accelerator foot pedal therethrough and then replaced over the floor element I0 and over the shaft I4 whereby, the device, except for the auxiliary accelerator foot pedal and the lever I5 or 15-29, is concealed from view.

While the device as shown and described is probably the preferred form of the device it is to be understood that such modifications cf the device may be employed as lie within the scope of the appended claims without departing from the spirit and intention of the invention. Now having fully shown and described my invention what I claim is:
